Winds that make a wind farm an attractive site can also make it a difficult project for crane operators

It’s strange to think about, but the very winds that make a wind farm an attractive site for producing electricity can also make it a difficult project for crane operators.

Over the last two months we have looked at the capabilities of cranes in maintenance and construction applications. This month we are going to discuss the wind in relation to the cranes themselves. There is a certain paradox in the fact that capturing the wind is the whole purpose of erecting a wind tower and […]

Validating tightness can help foresee failure issues in bolted flanges

Whether it’€™s a broken bolt found on the deck or a loosened nut discovered during a torque check, validating tightness can help foresee failure issues in bolted flanges.

Maybe you’ve heard this one before: “A technician walks into a wind turbine and finds a broken bolt lying on the floor.” Not as humorous as one might think, actually, because this means something above has come apart or is about to fail. If this technician has worked on turbines for years, he might recognize […]

Optimizing passive tuned mass dampers can greatly reduce loads in offshore floating wind turbines

Optimizing passive tuned mass dampers can greatly reduce loads in offshore floating wind turbines, leading to more viability in deep waters.

As offshore wind energy projects move farther offshore into deeper waters, wind turbines on floating platforms instead of the traditional fixed bottom platforms become more economical. Floating platforms have been used with success in the offshore oil industry, but there are a number of engineering challenges associated with offshore floating wind turbines (OFWTs). One important […]

A logistics quality system involving three basic elements will lead to better outcomes

A logistics quality system involving three basic elements ‘€”metrics/measurement, process/procedure, and reporting/repair’ €”will lead to better outcomes.

I am often asked how important quality systems are in logistics. I always answer by saying that it depends on the scope of the transportation. If the scope of transport is relatively noncritical, then the need is less than for critical transport. For example, a simple LTL—or “less than truckload”—transport requires less of the attention […]
